While driving home from work.. I was listening to NPR All Things Considered and came across a story called Missing: The Search For A Sister In China. It is about a Big Sister looking for her sister who has been missing for two years. She contacts Frank Langfitt to help her find her sister. The story is really interesting in the sense that even though this was a person you are related to and grew up with... her life was somewhat of a mystery. Take a listen if you get a chance.
What do you think happened to Little Sister? You can find a link to the story here.
